This should have the newer style battery holder. Can you post a picture of the MPU please?

Yes, I would go with NVRAM. NVRAM actually removes the need for batteries on the board. Can you post a better picture angled at the bottom of the battery holder? Need to see if we can tell if the board has corrosion.

In case you don't want to attempt installing a socket for the NVRAM, take a 30 minute drive out to Chesterfield, MO to see @chrishibler , who would be happy to do it for you.

Maybe he'll sell you one for TMNT as well, which the old RAM is in a socket that you can swap out yourself.

I imagine Chris would take care of it on the spot if you make an appointment to go see him. Considered minor damage from other boards I had worked on.

Alkaline batteries leak alkaline electrolyte, a base, not acid.

Just scrubbing with vinegar does not get it from under the solder mask. You can see the dark area around the one holder lead.

Quoted from McPin54:

Are you saying viniger has no effect alkaline?
This is for my info.

Removing damaged parts and sanding down the solder mask will get to the cancer that is the alkaline.

Read through the link that was supplied by YeOldPinPlayer and you'll see it is much more than work that one reaslizes.

Worse thing one can do is apply any heat to the side of the board that has been hit without sanding the solder mask of the damaged area and then treating it. It will be safe after that time.

Quoted from ForceFlow:

Actually, vinegar it's not acidic enough to do much of anything in this case.

Which is why the solder masking has to come of the board in the area that was damaged.

Don't worry @tonloc777, you cannot go wrong taking the board to Chris to get it taken care of.
